I purchased an app from Play Store on 8 Feb 2017,  the 9 Feb 2017 £1 was taken from my card.  On 27 Mar 2017 I downloaded a free app, the same day £1 taken from my card.   Today 6 Apr 2017 I uninstalled two apps and £1 was taken from my card.  I have now removed all payment methods from Google Wallet.
